Hello Sam
Long time no talk. How are you? I'm fine. 代我向 your parents 问好。
My parents ask about you. Everyone thinks of you. When will you visit us?
What the weather like?
In Thailand is very hot now, 泼水节 is coming,so everyone is waiting for it.
However,I wish you were here.
I hope to see you soon! Don't forget to keep in touch. Take care of yourself.
Best wishes.
